Somerfield specify their delivery down to a 2-hour slot.

So do Tesco's and, I believe, Iceland.com

I normally get my shopping done at a time when I expect to be at home
anyway for 2 hours on the same or following day.

I tried getting our shopping delivered from Tesco, but husband said he'd
rather see what we were buying, thank you very much, so he goes. But I
do get it delivered if it's stuff like a lot of water (still or
sparkling) or fruit juice that neither of us could carry, and we aren't
going past in the car at an appropriate time.
